Episode 3

In the third episode, the Metro's ageing fleet comes under pressure when a train breaks down in a tunnel near its busiest station. Meanwhile, track inspection supervisor Wayne has his work cut out repairing decaying sleepers which, if not quickly replaced, could cause a train derailment. And customer service manager Alan has to shelve his plans for a quiet evening after he's called in to deal with an outbreak of anti-social behaviour on the Metro.
